Fed Cup players participated in the "Tat-Who" challenge, in which they had to guess which tattoos belonged to which players.

Some of them were easy, such as the flowers on the right arm of former doubles No. 1 Bethanie Mattek-Sands.

Karolina Pliskova's leg tattoo was pretty identifiable as well, although it's possible to get her mixed up with her twin, Kristyna.

Both Pliskova and Timea Bacsinszky knew that Svetlana Kuznetsova has a tattoo that reads: "Pain doesn't kill me / I kill the pain."

Perhaps the most obvious of them all was the quote on Stan Wawrinka's forearm.

Pliskova had a hard time with the wings on the back of Gael Monfils, but Bacsinszky knew it. "He did it in Lausanne, in my city, so I know," she said.

Last, Aryna Sabalenka, to no one's surprise, guessed her own tiger tattoo with no problem.
